Patent CA-2082291-A1 (CA)
Inventor: AGRAWAL RAKESH
IPC: F25J3/04
Filed: 1992-11-06
Abstract: This invention relates to an improvement in a process for the separation of a multi-component stream by distillation.  A multi-component feed is introduced to a multicolumn distillation system comprising a first or main column and a side column wherein at least a light component A is separated from a heavier component C in the first column, the lighter component A being removed as an overhead fraction and the heavier component C being removed as a bottoms fraction.  In the distillation of a multi-component stream containing more than two components, e.g., components A, B & C or in the distillation of a binary stream containing components A & C and volatile impurities I for producing at least one component having dissimilar purity a side column is used for such separation and recovery.  The improvement for enhanced recovery of a component in the side column comprises withdrawing a liquid fraction from the main or first column at a point intermediate the overhead and bottoms and introducing that liquid fraction to an upper portion of the side column.  Lighter components are withdrawn from the side column and returned to an optimal location in the distillation system, typically the main column.  Reboiling in the side column is effected by removing a portion of the liquid typically from the bottom of this column and vaporizing this fraction against a vapor fraction obtained from the main column.  At least a portion of the vapor fraction from the main column is condensed and liquid is returned to an optimal point in the main column distillation system.  The vapor fraction withdrawn from the main column and used to vaporize the bottoms of the side column is withdrawn at a point below the liquid removal point for the liquid feed to the side column.

IPC: F21S9/02
Filed: 1993-01-12
Abstract: An apparatus for supporting a primary lamp and a secondary lamp is disclosed.  The apparatus comprises primary  and  secondary  brackets,  and  primary  and secondary sockets.  The primary socket is affixed to the primary bracket,  and  receives  the  primary  lamp, preferably  a  high  intensity  discharge  lamp.    The secondary bracket has a first end affixed to the primary bracket and a second end.   The secondary socket is affixed to the secondary bracket,  and receives the secondary lamp, preferably an incandescent lamp.   The primary bracket defines a projected perimeter.   The second end of the secondary bracket is normally biased to  an  operating  position where  the  secondary  lamp extends outside the projected perimeter of the primary bracket,  but can be moved to a maintenance position where  the  secondary  lamp  is  within  the  projected perimeter of the primary bracket.   In operation, the secondary lamp is thus spaced apart from the primary lamp.  During lamp replacement, however, the secondary bracket can be moved to a position where both lamps can be extracted from their enclosure.

Abstract: In a process for fabricating a multilayer printed circuit board with permanent innerlayers of photoresist, the photo-imageable composition used to form the hard permanent layer comprises a polymerizable acrylate monomer; an oligomer formed by the reaction of an epoxy resin and an acrylic or methacrylic acid; a photosensitive, free radical generating initiator for polymerization of the acrylic monomer and oligomer; a curable epoxy resin; a curing agent for the epoxy resin; and, optionally, a crosslinking agent reactive with hydroxyl groups. After exposure and development of a layer of the photoimageable composition and etching of the underlying metal layer on a board, the resultant photoresist is left on the circuitry traces.  The innerlayers of photoresist are stacked in a press where it initially conforms under heat and pressure to fill voids between the innerlayers and then cures to permanence.

Title: Apparatus and method for cutting soil and in situ construction of subsurface containment barriers
Inventor: CARTER ERNEST E JR
IPC: E02D31/00
Filed: 1992-06-22
Abstract: An apparatus for cutting soil and constructing containment barriers, such as for constructing a subsurface containment walls or bassins for contaminated material, comprises a beam (4) pivoted to a support (6) on the surface for abutting an extended length of soil (2a). The beam (4) comprises a cutting means for creating a cutting action against the extended length of abutting soil. The cutting means is preferably a conduit containing a plurality of jet ports through which high pressure fluid is ejected to impact the soil to be cut. The conduit is preferably rapidly reciprocated.  As cutting occurs, the beam (4) and the conduit pivot relative to the support to maintain the cutting apparatus adjacent the face of the soil (2a) to be cut. If the support is mobile, it can advance the cutting action by pulling the beam and conduit beyond the sector through which the beam (4) and conduit can pivot. A  method of cutting soil comprises generating cutting action along an extended locus of soil, and advancing the cutting action along a descending locus of the soil (2a) in response to gravity.

Abstract: PHN 13996                                        16.06.1992 ABSTRACT: CMOS integrated circuit.     An important problem in large integrated circuits is constituted by noise superimposed on the supply. This noise is particularly caused by switching of switching elements such as flipflops, and by heavily loaded output stages. These elements cause current peaks which may give rise to comparatively great fluctuations in the voltage. This problem is solved at least to a great extent in CMOS circuits with standard cells or with custom layout blocks by means of an additional decoupling capacitance in the form of an extra well in the routing channels The decoupling capacitance may be positioned immediately adjacent the switching element, which is favourable for suppressing the supply noise. Since the routing channels are generally not used anyway for providing circuit elements, the chip surface area is not or substantially not increased by this extra capacitance.            Fig. 3.

Inventor: UM GREGORY
IPC: H04N9/31
Filed: 1992-10-16
Abstract: Optical energy from a broadband source (12) is focused on an aperture (30) in an opaque member (16).  The energy exiting the aperture (30) is received off axis by a parabolic mirror (18) which collimates the energy. The collimated energy is reflected from each planar mirror of an actuated mirror array (20). The reflected energy from the mirror array (20) is reflected to the aper-ture (30) by the parabolic mirror (18). The orientation of each planar mirror determines the flux which passes through the aper-ture (30) or is reflected by a reflective face (28) of the opaque member (16). The energy reflected from this face (28) which is de-rived from each mirror corresponds to the flux intensity for a corresponding pixel. This energy may then be focused on a screen (24) to display the scene.
